function

`scipy.interpolate._polyint:BarycentricInterpolator.derivative`

source: build-install/usr/lib/python3.14/site-packages/scipy/interpolate/_polyint.py:886

Signature

def derivative(self, x, der = 1)

Summary

Evaluate a single derivative of the polynomial at the point x.

Parameters

x : array_like: Point or points at which to evaluate the derivatives
der : int, optional: Which derivative to evaluate (default: first derivative). This number includes the function value as 0th derivative.

Returns

d : ndarray: Derivative interpolated at the x-points. Shape of d is determined by replacing the interpolation axis in the original array with the shape of x.
